I don't know about the area that you're in but bad enough leaving your ipod in your car in direct sunlight. Even worst is if sunlight can get to it people can see it. You're just asking to have your car broken into.
70f degree weather, indirect sun, 40 gig ipod monochrome...4 hours, ipod was frozen dead. 2 days later it started working again out of no where.
That is so. cal. weather.
I've witnessed a car window explode from the heat inside, and I live in a not-so-warm part of the world. So I shudder to think what it could do to an iPod...
I run an iPod mini connected to an Alpine interface box connected to my head unit. As such, my iPod is in my glove box 99% of the time. The only time it leaves is to get synced up.
I live in Phoenix, Arizona.
For the unacquainted; it was 99 degrees yesterday and will only get worse.
Yeah, I'm in So. Arizona too and I've left my iPod in the glove box with no problems. I don't know about in direct sunlight, though, I think down here it would melt if I did that.
